Different types of resting melanocyte stem cells have unique characteristics and vary in their potential to become other cells.

Understanding where cancer cells come from helps create better prevention and treatment methods.

The extracellular matrix affects where tumors can start in the body.

Deregulation of stem cell function is central to the development of some cancers.

Skin cells and certain hair follicle areas produce hemoglobin, which may help protect against oxidative stress like UV damage.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Feather patterns are influenced by enhancers and chromatin looping, and the structure of protein complexes important for hair growth has been detailed.

Cellular and immunotherapies show promise for healing chronic wounds but need more research.

Stem cell therapies show promise for hair regrowth in androgenetic alopecia.
